bundle: optional multithreaded compression, ATM zstd-only Compression type can be a huge chunk of "hg bundle", especially when using the higher compression levels. With level=22 and threads=7, the NetBSD test repository took 28:39 wall time and 157:47 user time. Before, level=22 would take 129:20 wall time and 129:07 user time.

  * The `rev-branch-cache` is now updated incrementally whenever changesets
    are added.
 
+ * The new options `experimental.bundlecompthreads` and
+   `experimental.bundlecompthreads.<engine>` can be used to instruct
+   the compression engines for bundle operations to use multiple threads
+   for compression. The default is single threaded operation. Currently
+   only supported for zstd.
